URBANA, OH (AP) – A 17-year-old boy charged in an Ohio school shooting that wounded two students has pleaded not guilty by reason of insanity.

Ely Serna is charged with attempted murder, felonious assault and other offenses in the Jan. 20 shooting at West Liberty-Salem High School. His attorney entered Serna’s plea through motions this week in Champaign County Pleas Common Pleas Court.

Authorities allege Serna fired a shotgun at classmate Logan Cole in a school bathroom, critically wounding him, and then fired at classrooms. Another student was slightly injured at the school in West Liberty, about 55 miles northwest of Columbus.

The judge has ordered a competency hearing.

Serna’s case was transferred from juvenile court to adult court. Serna’s attorney has asked that it be transferred back to juvenile court.
